Is the method of regular startup and shutdown of virtual machine?

Recently, some content needs to be synchronized regularly by time. Is there a method to start or shut down the virtual machine regularly? By script or other methods?

It would be even more appreciated if you could provide a way to start or close Docker regularly！
